江苏开放大学程序设计基础形考第一次作业

江苏开放大学程序设计基础形考第一次作业作为一个资深的行业专家，我将为您提供关于江苏开放大学程序设计基础形考第一次作业的示例内容。示例内容：尊敬的江苏开放大学程序设计学员，欢迎参加本学期的程序设计基础课程形考。本次形考旨在评估您对程序设计基本概念和技能的掌握程度。以下是一份针对第一次作业的示例内容供您参考。作业要求：编写一个Java程序，实现一个简单的学生成绩管理系统。该系统应能够实现以下功能：-添加学生信息及其分数-查询并显示学生的平均分-查询并显示不及格的学生名单-查询并显示成绩最高的学生信息-查询并显示成绩最低的学生信息示例代码：下面是一个简单的示例代码，以帮助您开始完成这个作业：```javaimportjava.util.ArrayList;importjava.util.List;importjava.util.Scanner;publicclassStudentManagementSystem{publicstaticvoidmain(String[]args){List<Student>studentList=newArrayList<>();Scannerscanner=newScanner(System.in);while(true){System.out.println("欢迎使用学生成绩管理系统");System.out.println("1.添加学生信息");System.out.println("2.查询学生平均分");System.out.println("3.查询不及格学生名单");System.out.println("4.查询成绩最高的学生信息");System.out.println("5.查询成绩最低的学生信息");System.out.println("0.退出程序");System.out.print("请输入您的选择：");intchoice=scanner.nextInt();if(choice==0){System.out.println("程序已退出");break;}switch(choice){case1:System.out.print("请输入学生姓名：");Stringname=scanner.next();System.out.print("请输入学生分数：");intscore=scanner.nextInt();studentList.add(newStudent(name,score));break;case2:doubleaverage=calculateAverageScore(studentList);System.out.println("学生平均分为："+average);break;case3:List<Student>failedStudents=findFailedStudents(studentList);System.out.println("不及格学生名单：");for(Studentstudent:failedStudents){System.out.println(student.getName());}break;case4:StudenthighestScoreStudent=getHighestScoreStudent(studentList);System.out.println("成绩最高的学生信息：");System.out.println("姓名："+highestScoreStudent.getName());System.out.println("分数："+highestScoreStudent.getScore());break;case5:StudentlowestScoreStudent=getLowestScoreStudent(studentList);System.out.println("成绩最低的学生信息：");System.out.println("姓名："+lowestScoreStudent.getName());System.out.println("分数："+lowestScoreStudent.getScore());break;default:System.out.println("无效的选项");}System.out.println();}}privatestaticdoublecalculateAverageScore(List<Student>studentList){intsum=0;for(Studentstudent:studentList){sum+=student.getScore();}return(double)sum/studentList.size();}privatestaticList<Student>findFailedStudents(List<Student>studentList){List<Student>failedStudents=newArrayList<>();for(Studentstudent:studentList){if(student.getScore()<60){failedStudents.add(student);}}returnfailedStudents;}privatestaticStudentgetHighestScoreStudent(List<Student>studentList){StudenthighestScoreStudent=studentList.get(0);for(Studentstudent:studentList){if(student.getScore()>highestScoreStudent.getScore()){highestScoreStudent=student;}}returnhighestScoreStudent;}privatestaticStudentgetLowestScoreStudent(List<Student>studentList){StudentlowestScoreStudent=studentList.get(0);for(Studentstudent:studentList){if(student.getScore()<lowestScoreStudent.getScore()){lowestScoreStudent=student;}}returnlowestScoreStudent;}}classStudent{privateStringname;privateintscore;publicStudent(Stringname,intscore){=nam
